Feeding pigs with fermented pigeon droppings
With the large-scale breeding, the use value of pigeon droppings is getting bigger and bigger, and the nutrient content of the processed pigeon manure is not lower than that of other livestock manures. In addition, the pigeon manure feeds livestock and poultry to prevent certain diseases. Effect. Now we introduce the processing technology of pigeon droppings as follows:
dry
The ground is dry. The pigeon feces can be singly or incorporation of a certain proportion of wheat bran (about 20%), spread naturally in a sunny place and clean, and prevent rain. After drying can be saved for use. Pay attention to less than 14% moisture.
The greenhouse is dry. Spread pigeon feces on the ground of a plastic greenhouse, about 2 cm thick, until dry.
Silage
65% of pigeon droppings, 20% of grass powder, and 15% of bran so that the moisture content is kept at about 60% (clenched by hand without water) and put into a plastic bag (100 to 200 kg per bag). Sealed, leaving no dead ends, no air leaks, no water leakage. It can be used after 4 to 8 weeks.
Chemical treatment
The chemically treated pigeon droppings should be collected as soon as possible, mixed with 39% formaldehyde (formalin), and the amount of formalin added should be calculated as seven thousandths of dry pigeon droppings. Mix for 3 hours before use. In addition to other effects, the chemical treatment also has the effect of reducing the solubility of the protein and can increase the utilization of the protein.
Reasonable use
The processed pigeon droppings can be used to feed pigs, cows, sheep, ducks, etc. When it is added, it should be gradually and progressively. In general, the proportion of the first 5 days should not exceed 5%, and it should be increased by 5% every 3 to 5 days until 10% to 20%. When ducks are fed, they can be sprinkled on the ground to allow the ducks to feed freely and prevent duck plague.
Precautions
The above methods are aimed at the excrement of disease-free pigeons. The sick pigeon's feces should be removed.
Pigs produce fresh feces 108g
Since meat pigeons are fed with raw grains such as shredded corn, broad beans, wheat, etc., each row of pigeons eats 4.8g of raw grains dropped on the ground every day. 90% of them are corn kernels, which are collected and crushed to feed the pigs. .
Test feeding showed that pigs fed with fresh meat do not have adverse reactions to the feed and growth of pigs, indicating that it is safe and feasible to feed pigeons with pigeon feces. According to experiments, the use of pigeon feces to feed pigs can greatly reduce the amount of concentrate feed and reduce the feed cost by 60%. For every 1 kg of pig weight, the feed cost is reduced by 45% and the economic benefit is increased by 5.6%.
In addition, the use of fresh pigeons and feces to feed pigs can remove pigeon droppings in the pigeons' yard in time, improve the environmental hygiene of the pigeon farms, reduce the breeding of insects such as mosquitoes and flies, and greatly reduce environmental pollution.
